I currently have some of time on my hands (maybe other people as well) and I’d like to help Nix or NixOS. Are there any discoverable low-hanging fruits? I know some of the Nix language (not an expert though) and I’m fluent in C++.
There is currently an ongoing effort to fix build failures before the next release. That’s a very good option to get involved
Since you’re good with C++ it might be worth to take a look at the issues open in the nix repo https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc
